our livestream tomorrow at 10 am PDT will be longer than usual, around an hour. we have a lot to show and hope you can find the the time to watch!
someday soon something smarter than the smartest person you know will be running on a device in your pocket, helping you with whatever you want. this is a very remarkable thing.
My initial impression on OpenAI's OSS model is aligned with what they advertised. It does feel closer to o3 than to other open models, except it is much faster and cheaper. Some providers offer it at 3000 tokens/s, which is insane. It is definitely smarter than Kimi K2, R1 and
Today we release gpt-oss-120b and gpt-oss-20b—two open-weight LLMs that deliver strong performance and agentic tool use. Before release, we ran a first of its kind safety analysis where we fine-tuned the models to intentionally maximize their bio and cyber capabilities 🧵
gpt-oss is a big deal; it is a state-of-the-art open-weights reasoning model, with strong real-world performance comparable to o4-mini, that you can run locally on your own computer (or phone with the smaller size). We believe this is the best and most usable open model in the
gpt-oss is out! we made an open model that performs at the level of o4-mini and runs on a high-end laptop (WTF!!) (and a smaller one that runs on a phone). super proud of the team; big triumph of technology.
we have a lot of new stuff for you over the next few days! something big-but-small today. and then a big upgrade later this week.
we have a ton of stuff to launch over the next couple of months--new models, products, features, and more. please bear with us through some probable hiccups and capacity crunches. although it may be slightly choppy, we think you'll really love what we've created for you!
study mode in chatgpt is now rolling out to all free, plus, pro, and teams users! 📚🚀 this has been in the works for a while and i’m so excited we’re getting it out to the world today 🌎 i’ve always felt strongly about making education more accessible and intentional. with
we have signed a deal for an additional 4.5 gigawatts of capacity with oracle as part of stargate. easy to throw around numbers, but this is a _gigantic_ infrastructure project. some progress photos from abilene:
we are planning to significantly expand the ambitions of stargate past the $500 billion commitment we announced in january.
Congrats to the GDM team on their IMO result! I think their parallel success highlights how fast AI progress is. Their approach was a bit different than ours, but I think that shows there are many research directions for further progress. Some thoughts on our model and results 🧵
we will cross well over 1 million GPUs brought online by the end of this year! very proud of the team but now they better get to work figuring out how to 100x that lol
woke up early on a saturday to have a couple of hours to try using our new model for a little coding project. done in 5 minutes. it is very, very good. not sure how i feel about it...
Watching the model solve these IMO problems and achieve gold-level performance was magical. A few thoughts 🧵

1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
we achieved gold medal level performance on the 2025 IMO competition with a general-purpose reasoning system! to emphasize, this is an LLM doing math and not a specific formal math system; it is part of our main push towards general intelligence. when we first started openai,

We’ve activated our strongest safeguards for ChatGPT Agent. It’s the first model we’ve classified as High capability in biology & chemistry under our Preparedness Framework. Here’s why that matters–and what we’re doing to keep it safe. 🧵

We’ve decided to treat this launch as High Capability in the Biological and Chemical domain under our Preparedness Framework, and activated the associated safeguards. This is a precautionary approach, and we detail our safeguards in the system card. We outlined our approach on

watching chatgpt agent use a computer to do complex tasks has been a real "feel the agi" moment for me; something about seeing the computer think, plan, and execute hits different.
Today we launched a new product called ChatGPT Agent. Agent represents a new level of capability for AI systems and can accomplish some remarkable, complex tasks for you using its own computer. It combines the spirit of Deep Research and Operator, but is more powerful than that
this is a very cool one! live in 4 mins.

agree with lots of what jensen has been saying about ai and jobs; there is a ton of stuff to do in the world. people will 1) do a lot more than they could do before; ability and expectation will both go up 2) still care very much about other people and what they do 3) still be
